Description

In this session, Rohith Swaminathan from MIDAS IT Europe explores the unique complexities of Soil–Structure Interaction as applied to Integral Bridge design. Unlike conventional bridges with expansion joints, integral bridges feature a rigid connection between the deck and the abutments, making the soil response a critical driver of structural behavior.

The session covers the fundamental principles of integral bridge systems and demonstrates how MIDAS GTS NX can be used to accurately model the soil-abutment-deck interaction under a range of load conditions, including cyclic thermal movements and live traffic loads.

Participants will learn how to properly set up boundary conditions, apply earth pressure models, and interpret displacement and stress results in the context of abutment and pile foundation design. The session draws on practical project experience to highlight common modeling pitfalls and how to resolve them efficiently.
